The Optoma VR headset is also different from headsets like Sulon's Sulon Q and Microsoft's HoloLens, which are self-contained VR headsets and don't require PCs.

The Optoma headset has a 5.46-inch AMOLED screen with a 1920 x 1080-pixel resolution and a 90-degree field view. Simply called Virtual Reality Head Mounted Display, the headset was shown for the first time at the Game Developers Conference in San Francisco.

In a way, Optoma's device is an early demonstration of how cloud-based VR could work. Many 3D visuals for headsets are expected to be generated on remote computers, and then delivered to headsets via wireless or the Internet.

Wireless technology will also give users of the Optoma headset freedom to move around within the range of a PC. Oculus Rift users don't have freedom to move around.

Content is streamed from a PC to the headset using a proprietary wireless signal operating at the 60GHz band. Further details on the wireless technology weren't provided, but it could be UWB (ultrawide band) technology, which is faster than Wi-Fi.

The ultimate goal of VR is to deliver more life-like images at high frame rates from multiple sources. Future VR headsets could be full blown computers and have cloud-based VR elements like on Optoma's headset

No price has been set for the VR headset, but it will ship later this year.
